Hashed tables - This is the most appropriate type for any table where the main operation is key access. You cannot access a hashed table using its index. The response time for key access remains constant, regardless of the number of table entries. Like database tables, hashed tables always have a unique key. Hashed tables are useful if you want to construct and use an internal table, which resembles a database table or for processing large amounts of data.

SAMPLE PROG: THIS DOES NOTHING.

REPORT Z_1 .

TABLES: MARA.

DATA: I TYPE HASHED TABLE OF MARA WITH UNIQUE KEY MATNR
